base_image: add become privileges for custom image setup

Add become: true to tasks that require elevated privileges:
- Directory creation in libvirt storage path
- Writing to /etc/virt-builder/repos.d/

This fixes permission errors in CI environments where these
operations need root privileges to access system directories.

Resolves: PermissionError when creating custom image directories
